Lifeway Foods Inc. launched a reformulation of its bioKEFIR shots that may help promote immunity, digestion and heart health. Each 3.5-ounce, high-potency probiotic kefir shot is packed with 50 billion colony-forming units (CFUs) — twice the amount of the company’s regular kefir.

The functional shots category is doing well in the market, generating a triple-digit, 219.7% increase in year-over-year sales, according to SPINS’ data.
